What might link these
The relationship between these age groups might be influenced by societal factors such as education and workforce participation. A careful reader should consider that urbanization could be a confounder, as it affects both age distributions and economic indicators. The correlation persists even after controlling for population and GDP, suggesting a more complex relationship.
Why this is not proof of anything
This is a correlation across countries, not an experiment. It cannot show that either indicator causes the other, and both may simply follow a third thing. This correlation could mislead by implying a direct connection between the two age groups, when in fact they may be responding to broader demographic and economic trends.
The second figure above repeats the measurement with national population and income held constant. It is the more conservative number: a relationship that largely disappears there was mostly telling you that larger, richer countries have more of most things.
How this was measured
Both indicators were ranked across every country reporting each, and the two rankings compared — ranks rather than raw values, because a handful of very large countries can otherwise manufacture a relationship on their own. The calculation is arithmetic over figures already published on this site; the commentary above is drafted from the two indicator names and the resulting coefficients.
